BOX-FASTENER.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed June 29, 1908. Serial No. 441,005.

To all whom it may concern:

Be it known that I, GEORGE HENRY MAAS, a citizen of the United States, residin at Milwaukee, county of Milwaukee, and tate of Wisconsin, have invented new and useful Improvements in BX-Fasteners, of which the following is a specification.

My invention relates to improvements in that class of lock and seal for which Letters Patent of the United States, No. 878,215, was issued to me February 4, 1908, the same being adapted to be used in connection with shipping crates or cases.

The construction of my invention is explained by reference to the accompanying drawings in which,

Figure 1 represents a plan View of the cover retaining mechanism, removed from the cover, showing the parts which form the hasp supporting loop as they are cut preparatory to being bent into the required shape. Fig. 2 represents a vertical section of one corner of a shipping case and cover with the cover retaining mechanism drawn on line :za-:v of Fi 1. Fig. 3 represents a perspective view o a keeper formed for the reception of the hasp. Fig. 4 represents a detail view showing the inside view of the wall of the case, a vertical section of the cover and the keeper and a side view of part of the fastening mechanism co erating with such parts. Fig. 5 is a vertica section of the sealing member, which is inserted above the locking mechanism in the cover.

Like parts are identied by the same reference figures throughout the several views.

1 represents the cover retainin keeper which is rigidly aiiixed to the vertlcal wall 2 of the case, by a plurality of nails or screws 3. A wire hasp is pivotally connected with the cover through the loop 6 and seal supporting plate 7. The plate 7 is rigidly connected with the underside of the cover 8 by a plurality of nails or screws 9 and said cover and plate are locked in engagement with the wall 2 by turning the horizontal member 10 of the hasp beneath the vertical wall 11 of the keeper, as shown in Fig. 2. The hasp is formed of a piece of wire and comprises the horizontal member 10, the vertical member 12, horizontal member 13, vertical inverted U-shaped member 14 and horizontal member 15, which terminates in a U-shaped bend 16. The end of the U-shaped bend 16 is adapted to bear against the inside of the supporting loop 6 and serves as a spring to force the hasp into locking engagement with the keeper' 1. It will be understood that the horizontal members 13 and 15 and vertical member 14 taken together, serve as a lever for throwing the horizontal member 10 out of engagement with the keeper, when desirous to unlock the cover from the case.

For convenience of construction, the has retaining loop 6 and the plate 7 are formed integrally from a piece of sheet metal, which is first cut, as shown in Fig. 1 when the respective arms 18, 18, are curved downwardly and inwardly from the position, shown in Fig. 1, to that shown in Fig. 4, when the lower ends of said arms are brought together around the lower end of the vertical member 12, as indicated in Fi 4, the respective arms 18, 18, being provided with semi-circular recesses 19, 19, which, as they are brought together, form an aperture for the reception of the vertical member 12 of the hasp. The upper end of the vertical member 12 is supported from said plate 7 through the lug 20, which lug 20 1s formed integrally with the plate 7, said plate 7 being lirst provided wlth a U-shaped cut 21, as indicated in Fig. 1, when that part of the plate within the cut 21 is bent downwardly from the position shown in Fig. 1 to that shown in Fig. 4, when it thus serves as a support for said cover retaining hasp.

22 is an aperture formed in the cover for the reception of the U-shaped member 14 of the operating lever and seal. The plate 7 is provided with a circular aperture 23 terminating upon one side with two U-shaped recesses 24 and 25, for the reception of the vertical bend 14 of the operating lever, as is more clearly shown in Figs. 1 and 2.

It will be understood that when desirous to throw the horizontal locking member into engagement with the inclined wall 11 of the keeper', the vertical member 14 of the operating lever is thrown into the recesses 24 and 25, whereby the cover 8 is locked in engagement with the case. When however, it is desirous to remove the cover, the vertical member 14 of the lever is thrown back to the center of the aperture 22, whereby the horizontal member 10 is dis-engaged from the keeper, when the cover may be readily removed or raised from the case.

To prevent the locking mechanism from the case without disclosing such factlfhayn.

U4lower edge of .saidv .leeper, a vertical member provided my devicewith a sealing..meehan. ism 26. The sealing' member 2'6"'c`onpri`ses" the horizontal disk 27, annular sleeyeg2$f which sleeve is formed at right angles to and is connected with said horizontal meu-1ber27` by'a plurality of vertical lingers 29. Saidy seal also comprises a plurality Aof y'outwardly diverging tangs 30, all of which parts areformed integral with said disk 27. When the locking mechanism yhas been brought into engagement with the keeper, said sealing plate is inserted through the Aaperture 22 of the cover :and vaperture 23 5oi the plate 7, whereby the vertical loop ll 'of the operating lever iis retained in the recesses .24 .and 25 of said plate, and said cover retaining mechanism is prevented from being thrown out of locking engagement with ythe keeper. It

`will be understood that as the :sealing ydevice is 'thus forced into position, the retaining members 30 spring outwardly 'of their fown resiliency beneath the fastening plate 7, as shown in Fig. 5, whereby said sealing device :is .retained in place and it becomes impossible to dis-engage the locking mechanism without :first .breaking the plate 27 'from the :annular collar 28 of the sealing member. To facilitate in 4breaking the seal, the plate 27 is provided with apertures 3.1, 3l, for the reception of a breaking tool, which 'tool is inserted through one of the apertures 31, 'when by prying upwardly, 'the delicate connections 29 between the annular collar 28 and the plate 27 are readily broken, when the fo era-ting arm of the locking mechanism mayi e moved to the center ofthe aperture 22, whereby its `arm 1'0 will be dis-engaged from the lkeeper, when the cover may be thrown open 'or removed from the case.

The front wall 11 of the `keeper l is preferably formed Iat an angle to the vertical,

'converging inwardlyand downwardly from :its upper side toward 'the wall of the case, whereby as the `arm 10 of the hasp enters said keeper, it will be automatically turned toward `the wall tof the case, preparatory to being thrown back into locking engagement beneath t-he lower edge of the rhfasp bythe resilient action ofthe arm 16, 'as the cover .is lbrought to its closed position.

.Having thus described my invention what l lclaim as new and desire to secure by Letters Patent is,

l.. In Y'a ydevice ol the described class, the combination 'of a shipping case, :a keeper .rigidly 'atlixed to the walls ol the case, fa 'cover provided with an aperture for the :re- -ception of the operating arm of the lcover retaining hasp, a supporti-ng plate secured rto vthe inside of ,said cover, having a central aperture concentric with and of slightly less diameter than the 'aperture of said cover, a
